BIOMETRIC IDENTIFICATION MODULE
First Claim
1. A biometric identification module configured to obtain a fingerprint image of a finger, the biometric identification module comprising:
- a light source configured to emit a light beam;
a cover plate having a first region and a second region outside the first region, wherein the light source is located adjacent to the first region of the cover plate;
a display device;
an image-capture device, wherein the display device is located between the cover plate and the image-capture device; and
a first optical film layer disposed on the first region of the cover plate and located between the first region of the cover plate and the light source, wherein the light beam emitted by the light source passes through the first optical film layer to be sequentially transmitted in the first region and the second region of the cover plate, a finger disposed on the second region of the cover plate reflects the light beam from the second region of the cover plate, and the light beam reflected by the finger sequentially passes through the second region of the cover plate and the display device to be received by the image-capture device.

Abstract
A biometric identification module including a light source, a cover plate, a display device, an image-capture device, and a first optical film layer is provided. The display device is disposed between the cover plate and the image-capture device. A first optical film layer is disposed on a first region of the cover plate and located between the first region and the light source, wherein the light beam emitted by the light source passes through the first optical film layer to be sequentially transmitted in the first region and a second region of the cover plate, and a finger disposed on the second region of the cover plate reflects the light beam from the second region of the cover plate. The light beam reflected by the finger sequentially passes through the second region of the cover plate and the display device to be received by the image-capture device.
